Q of the given QTRS could be proven: (0) QTRS (1) QTRSRRRProof [EQUIVALENT, 56 ms] (2) QTRS (3) RisEmptyProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: __(__(X, Y), Z) -> __(X, __(Y, Z)) __(X, nil) -> X __(nil, X) -> X and(tt, X) -> activate(X) isNePal(__(I, __(P, I))) -> tt activate(X) -> X Q is empty. ---------------------------------------- (1) QTRSRRRProof (EQUIVALENT) Used ordering: Polynomial interpretation [POLO]: POL(__(x_1, x_2)) = 1 + 2*x_1 + x_2 POL(activate(x_1)) = 2 + x_1 POL(and(x_1, x_2)) = 1 + 2*x_1 + x_2 POL(isNePal(x_1)) = 1 + 2*x_1 POL(nil) = 2 POL(tt) = 1 With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly: __(__(X, Y), Z) -> __(X, __(Y, Z)) __(X, nil) -> X __(nil, X) -> X and(tt, X) -> activate(X) isNePal(__(I, __(P, I))) -> tt activate(X) -> X ---------------------------------------- (2) Obligation: Q restricted rewrite system: R is empty. Q is empty. ---------------------------------------- (3) RisEmptyProof (EQUIVALENT) The TRS R is empty. Hence, termination is trivially proven. ---------------------------------------- (4) YES
